    Great product!

    I used the Thermal Grizzly PhaseSheet PTM on my GPU, and I am impressed with the results. The pad is easy to cut to size and applies evenly. My GPU temperatures are lower, and I no longer hear the fan running at high speeds constantly. It’s a good product that performs well and feels durable. I would recommend it to anyone looking to enhance their cooling setup.

    Outstanding thermal performance without the mess

    The Thermal Grizzly PhaseSheet PTM is an exceptional alternative to traditional thermal paste. Installing it on my GPU/CPU was straightforward—just cut to size, apply, and pull off the protective film. Under load, temperatures dropped noticeably compared to stock paste, and thermal throttling is completely gone. Because it’s a phase-change material, it turns semi-liquid under heat to fill micro-gaps perfectly, but cools back down without pump-out issues or messy re-applications down the road. Highly recommended if you want liquid-metal-like performance without the risk of conductivity!

    Thermal Grizz PTM

    Amazing thermal interface solution offered by Thermal Grizzly. I would recommended to anyone using a laptop or similar compact devices to upgrade to this product. Average temperatures dropped immediately after installation by 10°+ compared to the stock thermal paste provided by manufacturer

    Thermal Grizzly Phasesheet PTM

    Product was delivered quickly. I recommend chilling it in the fridge for 15 minutes before installing it. Cut to size to fit my Ryzen 9 9950x3d processor, and after thermocycling it 10+ times, I'm getting 76 degrees Celsius in the Cinebench 2026 multi CPU benchmark.

    Easy to use and effective

    Just like the instructions say, you can cut this to shape and size of your cards and press on, remove the film, and you’re set. Dropped my temps to 38 degrees baseline on my MSI GS66 Stealth. Great purchase.

Thermal Grizzly - PhaseSheet PTM 50x40mm – High-Performance Thermal Pad | Durable, Non-Conductive CPU/GPU Cooling
5.0(5)

The phase-change material on which the PhaseSheet PTM is based is solid at room temperature. The material only begins to liquefy at temperatures above 45 degrees Celsius. A high contact pressure of around 300-400N is required for optimum distribution of the liquid PhaseSheet PTM and thus the lowest possible layer thickness. PhaseSheet PTM has a very low viscosity in its liquid state and contracts again when it changes to a solid material, thus minimizing the pump-out effect. The pump-out effect is particularly pronounced when combining a copper cooler on a graphics chip because silicon and copper have different linear expansion when heated. The temperatures under load cause the heatspreader and the base plate to deform (concave or convex) and return to their original shape (straight) when they cool down. As a result, the thermal paste is slowly pressed out between the heatspreader and the base plate of the CPU cooler, for example. Outstanding thermal conductivity consistently high performance Very long service life Versatile in application Not electrically conductive Easy to use PhaseSheet PTM is more durable than traditional thermal pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. PhaseSheet PTM develops and stabilizes its maximum thermal conductivity after around ten thermal cycles above 60 degrees Celsius. Scope of Delivery 1x PhaseSheet PTM
